This invention relates to improvements in water heaters and has'for itsprincipal object to provide a means for electrically heatingwater in acasing rapidly upon the dis- 5, charge of the water from the supply pipeinto the/casing.

A further object of the invention is to provide a rapidly electric waterheater of the above mentioned charactenwhich will at all times bepositive and eflicient in its operation, the parts being so arranged asto enable the same to be readily and easily assembled for use. A furtherobject of the invention is to provide an electric water heater wherein.a plus rality of spray pipes are arranged within the casing fordirecting the flow of water therethrough onto the heating elementwhereby the water may be'rapidly heated and discharged from the casing.

A- still further object of the invention is to provide a water heater ofthe above mentioned character, which is-simple in co'n-. struction,inexpensive, strong and durable, and furthermore adapted for thepurposes for which it'is'desi ated.

Other objects an advantages of this invention will become apparentduring the course of the following description; so In the accompanyingdrawing formin a part of this s ification and in which like numeralsdesignate like parts throughout the same:

nt e rawingw erein or e urpoeeo illustration is shown the preferred'iembodiment of my invention, the numeral 1 designates a substantiallycylindrical forming a part of my im roved electric water heater, theupper en thereof being fur,- ther provided with anmwardly disposedinternall threaded neck 2, the puaoee of which will be presentlydescribed. mmunicating with the bottom 8 0i the 1 iatheoutletpipei iExtending vertically .within the cyhndrlcal casing 1 and arranged inspaced relation with respect toeachother are the spray pipes 5.'lhelower ends oi the spray 131w are supported in suitable sockets 6,extending from the inner wall of the casing adjacent the bottom 3, whilethe upper ends of the pipes extend through the top of the casing in themanner as illustrated more clearlyin Figure 1. Any additional means maybe 00 provided for supporting the pipe in proper spaced relation withrespect to each other within the casing and each of the pipes isprovided with a plurality of vertically spaced jets, 7, whereby thewater flowing through the pipes will be directed. out through the jetsonto theheater disposed within the casing and the construction of whichwill be presently described. I

A main supply pipe 8 communicates with 7 the upper'ends of thevertically extending spray pipes 5, by means of the branch pipes 9, andthis construction .is clearly illustrated in Figure 2 of the drawing.The opposite r end of the main supply pipe 8 may be connect- 7 ed to anysuitable water supply (not shown) Extending centrally and verticallywithin the casing 1 is the hollow core 10 which may be constructed ofany suitable non-conductive material, the bottom of the core beingclosed as illustrated at ll. The upper portion of the core 'isexternally threaded as illustrated at 12 whereby the samemay besupported in engagement withthe internally threaded neck 2 formed in thetop of the casing so that the bottom 11 of the core will be spaced fromthe bottom 3 of the casing. An insulator 13 is disposed \vithin the core10 and is spaced therefrom and extending around the insulator 13 is theresistance 00 wire 14. A 'plug 15 is associated with the 1 up er end ofthe core and the contacts 16 and 17 thereof are adapted to be connectedto the resistance 14 and a suitable source of electric supplyrespectively in the manner 05 well known in the art.

When the plug 15 is attached to an electrnsocket, the current will flowthrough the resistance wire 14 heatingthe hollow core 10- and causingthe same to maintain its heated condition as long as is desired. Asupply of water is admitted to the spray pipes 5 from the suppl pipe 8and as the water passes through tlie pipes 5, the same will bedischarged out through the jet 7 against the 108 001:6 10 whereby thewater will be heatedand theheated .water will be discharged frpm the outthrough thc dlscharge pipe ll invention an The plicity in which myimproved I electric water heater is constructed enables the partsto bereadily assembled on disassembled and the heating means may be readilyremoved from the casing without the loss 0 any considerable length oftime and labor.

While I have shown the referred embodiment of my invention, it 15 to beunderstoodthat various changes in the size, sha and arrangementof partsmay be resorted to without departing from the spirit of the claims.

Having thus described 1 the invention, what I claim is 1. An electricwater heater comprising a '29 cylindrical casing, an outlet pipeextending its upper end in the internally threaded from the bottomthereof, a plurality of spaced water s ray pipes extending verticallywithin t e casing against the inner wall thereof, a supply having meansie for communicating with e upper ends of the spra pipes, said s series0 vertically spa ets, an electric heater supported centrally withm andagainst which the water from the spray 31y pipes having a the scope ofthe appended the in the mam supply pipe with the upper through the jetscomes in contact withv 30 pe ing internally threaded neck in t e top ofthe casing, a plurality of spaced water spray pipes extending verticallywithin the casing, a main supply pipe, branch pipes connecten s of thespray plpes, each of spray pipes having a series of vertically spacedjets, and an electric heating member supported at neck of the casing,the lower end of the heating member being spaced from the bottom of thecasing, the water in the s ray pipe adapted to be dischar ed throug thejets onto the heating mem r before being discharged from the casingthrough the outlet 66 i p ll- 1 testimony whereof I aflix my si ature.
